hey guys i have a 1994 k1500 with a tbi 350. Ive put a k&n stock style air filter with the airbox lid flip. Also it has a 2 into 1 single pipe with a magnaflow muffler and stock cat. It runs great and has 182,000 miles but i want a little more power without a engine swap or major engine work. Im looking for like bolt on stuff mainly possibly true duals combined with some other modifications. Any opinions on what to do? I have a old edelbrock 4 barrel off of a 350 but idk if i wanna do a carb swap

true dual will hurt more than help....i had the single sided Flowmaster on my '90 Blazer as i was preparing to do a few modifications. very important is to get some good flow matched injectors....

look at this site, from what i gathered at the time he's regarded as very good with the TBI platform and programming.

gearing could be your friend too.

Headers for sure......make sure your tbi is at 12p.s.i.,,Y-pipe would be at the top and true dual won't hurt at all

I'm willing to bet your hurting power with that intake setup. Ditch the k&n and get a good stock style filter. Flip the lid back down so your pulling in outside air not hot under hood air.

Rebuild engine cam swap .430/.450 int/exh if keeping tbi stock. Add 2-3 degrees timing just before check engine light comes on driving.
182k not worth sinking $ just to break something.
If it was mine 5.3 ls swap
